DISTRIBUTION OF WATER IN HOUSES.

SPECIFICATION forming part of Letters Patent No. 277,691, dated May 15,1883.

Application filed July31,1882. (No model.) Patented in France March 24,I882, No. 148,066; in Belgium June 10,. 1882, No. 5r-',15-l;

in England June 16, 1882, No. 52,850, and in Germany July 23, 1882, No.21.309.

To all whom it may concern Be it known that I, ANTHELME DUMAS, a citizenof the Republic of France, and residing in- Paris, France, have inventedcertain Improvements in the Distribution of Water in Houses and in theapparatus connected therewith, of which the following is aspecification.

My invention relates to an improved system of and apparatus forsupplying and distributing water in and to houses and other places; andit has for its object obviating the disadvantages of the systems atpresent in use by the employment of a simple and inexpensive arrangementof apparatus capable of working with regularity and precision.

The object of my invention is to equalize the distribution and flow ofWater in the delivery pipes and cooks in houses, dwellings, 850.; andthis object I attain by combining with the supply-pipe a reservoir,pipes, and a delivery-valve constructedsubstantially as hereinafter setforth.

In the accompanying drawings, Figure 1, Sheet 1, is a side view of myimprovement; Fig. 2, Sheet 2, a sectional view of the delix ery-cock,and Fig. 3 a detached view of the cam for operating the valves of thedeliverycock.

A tank or reservoir, to, preferably cylindrical, and provided with arounded cover, I), and bottom I), is secured in position near eachdelivery-valve e. The upper part of the reservoir communicates with twopipes, cand (l, the former, preferably of small diameter and providedwith a valve, 0, being the water-suppl y pipe, while the pipe (lcommunicates with one of the valved passages in the cock 6, which is adouble cock, as more fully described hereinafter. The bottom of thereservoir communicates, through the pipef,with the other valved passagein the delivery'pipe e. As shown in Fig. 2, the valve 6 has twopassages, g and Ii, the former for the escape of the water and thelatter for the simultaneous admission of air to the reservoir. Thepassageg is provided with a valve, g, normally kept to its seat 9 by aspiral spring, 9 The passage It has a valve, h, at right angles to thevalve g, and normally kept to its seat 7L2 by a spiral spring, ]L3. The

noses of both valves are in contact with a cam, I

i, adapted to bearings in the casing and controlled by a handle, 11,sothat when the latter is turned in the direction of the arrow,Fig.2,

the cam i will simultaneously open both the valves 9 and h, and, whileallowing the water to escape from the reservoir, will admit air to theupper part thereof, and so equalize the flow ot' the water therefrom.The employment of the reservoir, moreover, obviates the objectionableshocks and noises which are due to the sudden arresting of the flow ofthe column of water in the ordinary pipes, and also petmits me to usesupply-pipes of comparatively small diameter.

I claim as my invention- I The combination of. a water-supply pipe, 0,reservoir 0, and double delivery-cock with air and water pipes (If,connecting the reservoir with the said double coclr, substantially asdescribed.

In testimouy whereotl have signed my name to this specification in thepresence of two subscribing witnesses.

ANTHELME DUMAS.
